Power testing failed red point at 12V , Green are OK -5V

Hello,

I am stuck already with the power testing
So all red points are 12V and greens points are ok at -5V…
My DC Adaptator is a 9V (200mA) positive
any thought where I should check first?

Thanks

Brice

Is the 7805 correctly soldered? What are the voltages at each of its three pins?

Ok, sorry it’s fine, the LT 1054 wasn’t pushed enough…

Let’s continue! :wink:
